I've cut off contact with 99% of my family and I have not once regretted that decision. Why I did it isn't something I care to go into details about as this is the internet and all, but I will say that they are all very unhealthy people and I did not have the time to invest in relationships with "family" who do literally nothing to help themselves.

From your description of how your family has been affecting you, you're doing the right thing. You shouldn't have to put up with people who are robbing you of your emotional and mental health even if it's your family who sounds like they don't bother acting like a family should act.

Keeping a record of any harassment is a good idea, that can come in handy later if things start to escalate.

Cutting ties with my family was far easier on me emotionally as I am a Narcissist, but it still wasn't a cake walk as a few of my family members simply do not understand the concept of boundaries and just letting something the **** go already. I kept a record of the ones that were harassing me and filed reports when I had enough information, and frankly I found it funny that they were stupid enough to mess with me when I warned them very clearly what would happen if they continued to annoy the ever living **** out of me.

I wish you all the best with your decision. I am horrifically bad at emotional support obviously ha ha ha, but if you need practical advice about how to deal with this kind of situation you are more than welcome to send me a message. As I said, I think you're totally doing the right thing and you do have my support albeit it isn't out of empathy but out of logic.
